DE102016225377A1 - Creamy Hair Dye II - Google Patents

Abstract

The present invention relates to oxidative hair dyeing compositions containing 65-83% by weight of water, oxidation dye precursor (s), alkalizing agent, and a specific mixture of a crosslinked copolymer of acrylic acid and non-ethoxylated acrylic acid esters with linear C10-C30. Monoalcohols, glyceryl fatty acid esters, selected fatty alcohol ethoxylates and linear, saturated C8-C22 alkan-1-ol, whereby the colorant obtains an application-optimal viscosity and the consistency of a gel-like cream with excellent feel.

Description

The present application relates to an oxidative hair colorant in cream form, a kit comprising this colorant and a hair dyeing method using this colorant.

For permanent, intensive dyeings with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes. The oxidation dyes are characterized by excellent, long-lasting dyeing results. For naturally acting dyeings, however, it is usually necessary to use a mixture of a larger number of oxidation dye precursors (OFV); In many cases, direct dyes (DZ) are still included for shade.

For the most part, oxidative colorants for stabilizing the dye precursors during storage and for accelerating the reaction during the oxidative application have an alkaline pH adjusted with alkalizing agents, such as alkanolamines, ammonia or inorganic bases.

To form the dye, the alkaline dyeing component is usually mixed with an aqueous hydrogen peroxide solution to form a homogeneous cream or a homogeneous gel and applied directly to the hair to be dyed. This dye mixture remains on the hair for a period of 5 to 60 minutes until the oxidative formation of the dye on the hair is completed. Subsequently, the dye mixture is washed out.

The abovementioned oxidation dye precursors (OFV) and alkalizing agents are usually incorporated in a cosmetically suitable vehicle, for example a cream. The carrier ensures a homogeneous distribution and a sufficient residence time of the hair dye on the hair.

The present invention was based on the object to provide an oxidative hair dye, which has a creamy consistency, feel and appearance at constant to increased viscosity while reducing the content of high-melting, thickening fat components.

Particularly preferred is steareth-100. According to the invention, particularly preferred and particularly preferably used agents contain 0.1-2% by weight, preferably 0.2-1.5% by weight, particularly preferably 0.4-1% by weight of steareth-100, in each case based on the weight of the agent.

The compositions according to the invention and those used according to the invention furthermore contain at least one linear, saturated ethoxylated 1-alkanol having 8 to 22 carbon atoms in the alkyl radical and a degree of ethoxylation of 20 to 50, preferably 30-35, in a total amount of 0.1-2% by weight. , preferably 0.2 to 1.5 wt .-%, particularly preferably 0.4 to 1 wt .-%, each based on the weight of the composition.

Preferred linear, saturated 1-alkanols having 8 to 22 carbon atoms, which are part of the ethoxylated 1-alkanols according to the invention having a degree of ethoxylation of from 20 to 50, preferably 30-35, are selected from octan-1-ol (octyl alcohol, capryl alcohol), Decan-1-ol (decyl alcohol, capric alcohol), dodecan-1-ol (dodecyl alcohol, lauryl alcohol), tetradecan-1-ol, (tetradecyl alcohol, myristyl alcohol), hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol), octadecane-1 -ol (octadecyl alcohol, stearyl alcohol), eicosan-1-ol (eicosyl alcohol, arachyl alcohol) and docosan-1-ol (docosyl alcohol, behenyl alcohol). In turn, hexadecan-1-ol and octadecan-1-ol are very particularly preferred 1-alkanols within this group.

In the course of the work leading to this invention, it has been found that the degree of ethoxylation of the moderately ethoxylated (20 to 50, preferably 30 to 35 EO) 1-alkanol surprisingly in conjunction with the at least one above-mentioned highly ethoxylated (80-120 EO) 1 -Alkanol significantly affects the thickening properties and consistency of the composition. For this reason it is particularly preferred if one or more linear, saturated ethoxylated 1-alkanols having a very specific degree of ethoxylation are used.

By polymers are meant macromolecules having a molecular weight of at least 1000 g / mol, preferably of at least 2500 g / mol, more preferably of at least 5000 g / mol, which consist of identical, repeating organic units. Polymers are made by polymerization of a monomer type or by polymerization of different structurally different monomer types. If the polymer is prepared by polymerization of a monomer type, one speaks of homopolymers. If structurally different monomer types are used in the polymerization, the person skilled in the art will speak of copolymers.

The maximum molecular weight of the polymer depends on the degree of polymerization (number of polymerized monomers) and is determined by the polymerization method. For the purposes of the present invention, it is preferred if the molecular weight of the zwitterionic polymer is 100,000 to 10 ⁷ g / mol, preferably 200,000 to 5 x 10 ⁶ g / mol and particularly preferably 500,000 to
1 x 10 ⁶ g / mol.

Zwitterionic polymers are understood as meaning those polymers which contain both cationic groups and anionic groups in the macromolecule. The cationic groups contained in the macromolecule are quaternary ammonium groups. In these quaternary ammonium groups, a positively charged nitrogen atom carries four organic residues. The anionic groups are -COO ^- or -SO ₃ ^- groups.

The cationic polymers may be homopolymers or copolymers or polymers based on natural polymers, wherein the quaternary nitrogen groups are contained either in the polymer chain or preferably as a substituent on one or more of the monomers. The ammonium group-containing monomers may be copolymerized with non-cationic monomers. Suitable cationic monomers are unsaturated, radically polymerizable compounds bearing at least one cationic group, especially ammonium substituted vinyl monomers such as trialkylmethacryloxyalkylammonium, trialkylacryloxyalkylammonium, dialkyldiallylammonium and quaternary vinylammonium monomers having cyclic cationic nitrogen containing groups such as pyridinium, imidazolium or quaternary pyrrolidones, e.g. Alkylvinylimidazolium, Alkylvinylpyridinium, or Alkylvinylpyrrolidone salts. The alkyl groups of these monomers are preferably lower alkyl groups such as C1 to C7 alkyl groups, more preferably C1 to C3 alkyl groups.

The ammonium group-containing monomers may be copolymerized with non-cationic monomers. Suitable comonomers are, for example, acrylamide, methacrylamide; Alkyl and dialkylacrylamide, alkyl and dialkylmethacrylamide, alkylacrylate, alkylmethacrylate, vinylcaprolactone, vinylcaprolactam, vinylpyrrolidone, vinylester, e.g. Vinyl acetate, vinyl alcohol, propylene glycol or ethylene glycol, wherein the alkyl groups of these monomers are preferably C1 to C7 alkyl groups, more preferably C1 to C3 alkyl groups.

The comparison of the two comparative compositions V1 and V2 shows that an addition of 0.05% by weight of acrylates / C10-30 alkyl acrylate crosspolymer still has no appreciable influence on the viscosity of the cream. On the other hand, with the addition of an amount of acrylates / C10-30 alkyl acrylate crosspolymer according to the invention, there is almost a doubling of the viscosity (viscosity increase by 1.8 times).

The addition of 0.5% by weight of acrylates / C10-30 alkyl acrylate crosspolymer (see E4 and V1) makes it possible to reduce the amount of fatty phase by 10% by weight without losing viscosity. The reduction of the amount of fat phase by 10% by weight alone, without addition of acrylates / C10-30 alkyl acrylate crosspolymer, leads to a complete loss of emulsion stability (compare V3 and V1).
